I do not mean that your wife is a terrorist or a money launderer. You should try and understand me. There are ways those coins can get into the good peoples hands also. That is the reason I concluded it with 'if I am clean and not violate anything, I will continue to disturb the exchange. I will prefer the live chat'.
And now you have a better explanation that the money is from Binance, then best to continue to contact their support was my suggestion.
Clearly, its important to know fund from sender money laundering or not before withdrawing to other exchange market, inside fund receiving from good people or not but most important to know many exchange easily to seize our account after getting report from sender as we have pay them or not.
Still remember with my friend Binance account have seized more than one month after buying cryptocurrency fund from unknow person, suddenly fund receiving report by them and Binance take action for seize awhile until the transaction clearly. Give all proof if fund receiving from good people and give them fully transaction history how to recovery back fund if getting an exchange account seize, I believe always have way get recovery back account exchange after seize.
